First a quick note... drives LTO 2nd generation and newer should not shoeshine unless you're really running way to slow a cpu for what else is going on with the computer.
If the room air temp is less than 85 degrees or so it's unlikely in a tape autoloader cabinet (i.e. good airflow by design) that you've got a heat problem, imho. More likely is that you're filling up space somewhere, have a scsi issue, perhaps you need a firmware update to your library/drive, or need update to a more recent bacula server version due to some of the various spooling and multi-drive autochanger related bugs, or have a config problem. You should be able to put a thermometer near the drive to find out the exact air temp near it. Also, have you considered spooling everything? I know this may slow down your backups on fast servers but the increase gained in doing more than one thing at a time may balance this, especially on incrementals. > Date: Wed, 27 Feb 2008 09:31:40 +0000 > From: Bob Cregan <[EMAIL PROTECTED]> > Subject: Re: [Bacula-users] Volumes marked with Error > To: bacula-users@lists.sourceforge.net > Message-ID: <[EMAIL PROTECTED]> > Content-Type: text/plain; charset=ISO-8859-1; format=flowed > > Hi, > I am running the following > > Director, Storage deamon 2.2.6.
